STUDY ON BLOCK ASSEMBLING METHOD OF SHIP HULL CONSTRUCTION

In recent years we have advanced various kind of rationalization such as establishment of workshops, improvement of working environments and automation of works, and have gradually achieved the effective work method. Rationalizations like these have been started with adoption of assembly of blocks on assembly yard and afterwards, has been developed in the field of assembly of blocks in parallel with the progress of welding technique. Since assembly of blocks made the most contribution toward the rationalizaiton of shipbuilding practice, and will also play a vital role in the future, we consider it necessary to make a systematic study of the block assembling method, which will help us develop and improve it. From this point of view, the authors are examining the significance of the block assembling method and the development of production engineering for assembly of blocks, and are quantitatively comparing major assembling methods in terms of production hours which have a great influence on production cost.
